Door closer device

Abstract

A door closer device for driving a door to a predetermined closed position includes an adjustment mechanism and a door closer which is integrated with the door. The adjustment mechanism includes a base, an adjusting plate and at least one fixing element, wherein the adjusting plate is stacked with the base and coupled with the door closer. The adjusting plate and the base respectively include at least one adjusting bore, and the adjusting bores are corresponding with each other. One of the adjusting bores includes a first limiting end and a second limiting end, and a first moving path is defined between the first and second limiting ends. The fixing element is disposed in the adjusting bores and can move along the first moving path to fix the adjusting plate on the base.

What is claimed is: 
     
       1. A door closer device comprising:
 a door closer including a rotating shaft; and 
 an adjustment mechanism including:
 a base including an accommodation part and a first adjusting bore with a first limiting end and a second limiting end, wherein a first moving path is defined between the first and second limiting ends; 
 an adjusting plate stacked with the base and including:
 an axial bore aligned with the accommodation part, wherein the rotating shaft is coupled to the axial bore; 
 a second adjusting bore corresponding with the first adjusting bore of the base and including a third limiting end and a fourth limiting end, wherein a second moving path, perpendicular to the first moving path, is defined between the third and fourth limiting ends; 
 a surface facing the base; and 
 a fixing base protruding from the surface and disposed in the accommodation part such that a space is defined between an internal side surface of the accommodation part and an external side surface of the fixing base; and 
 a fixing element disposed in the first and second adjusting bores and movable along the first or second moving path to fix the adjusting plate on the base. 
 
 
 
     
     
       2. The door closer device in accordance with  claim 1 , wherein the base further includes a first joint bore and the adjusting plate further includes a second joint bore and the first and second joint bores correspond with each other, and wherein a joint element is disposed in the first and second joint bores. 
     
     
       3. The door closer device in accordance with  claim 2 , wherein the joint element includes a first joint portion and a second joint portion, and the first and second joint portions are eccentric. 
     
     
       4. The adjustment mechanism of door closer device in accordance with  claim 3 , wherein the adjustment mechanism further includes a coupling element disposed in a through hole of the adjusting plate contacting the second joint portion. 
     
     
       5. The door closer device in accordance with  claim 4 , wherein the base further includes an opening communicating with the accommodation part and wherein the adjusting plate is located in the accommodation part and the opening reveals the through hole. 
     
     
       6. The door closer device in accordance with  claim 1 , wherein the adjustment mechanism further includes a positioning element, the adjusting plate further includes a positioning hole, the positioning element is disposed in the positioning hole, and a front terminal part of the positioning element contacts the base. 
     
     
       7. The door closer device in accordance with  claim 1 , wherein the door closer further includes a case, a cam, a roller group and a piston, the cam, the roller group and the piston are disposed within an accommodation space of the case, the cam is located on the rotating shaft, the roller group has a first roller and a second roller located on both sides of the cam, respectively, and the first roller is coupled with the piston.
